Wallaroo Location

-33.9333, 137.6167

-33.93330, 137.61670 View on OpenStreetMap →

Wallaroo sits at -33.9333°N, 137.6167°E, on the coast of South Australia, Australia. The marker on the map shows the spot the readings on this page come from. It usually sits a short distance from the town centre, out on the open water itself, so the numbers stay tied to the coast rather than a generic point inland.

Coastlines bend, headlands focus the water, and the temperature can run noticeably differently between two beaches that look close together on a map. Comparing nearby locations is a quick way to see how local geography is shaping the readings.
